Dw not filling maytag mdb4949sdz0

E1 f6

maytag mdb4949sdz0
The error code is E1 f6.
When I push start, it begins to fill for a few seconds and stops for several seconds.  Then tries to fill again for a couple of seconds and stops.  If I leave it alone for a minute or two, it will drain and try to refill, but only for a couple of seconds again.  I replaced the water inlet valve.  No change. Thoughts?

Sounds like you might have a faulty float switch. 

Have you verified that you have water coming into the unit ?

 

[AngelaGriffin]

Replaced float switch. Same problem exists. Metered the old switch at 0.2 ohms. New switch tested at 0.4 ohms. So I have replaced the float switch, door latch switch, and inlet valve.

 

Door latch 0.4* old, 0.3* new

Inlet old 1.388*, new 1.41*

Runs longer but won't fill all the way. Checked the hose, no obstructions. Float acts correctly.

Have you checked for 120v at the valve? Is the voltage dropping out when the valve turns off?

[AngelaGriffin]

The voltage at inlet is in the range of 120.2 volts ac. It stays that way for about 1 minute then drops down to 11.87 volts.

I am assuming that it is trying to turn off. I'm not sure what you mean by turn off. 

Thank you. I appreciate your help.

I'm sorry I realized I didn't answer your question. I had put my phone in the dishwasher on the top rack. It shows water coming in. The video is larger than 500. I loaded it on my Twitter account. It doesn't show me putting it in the Dishwasher, but I loaded up the amount it would allow. Thank you. Appreciate your help.

I couldn’t find that model number. 
 

my guess is bad check valve in drain hose. The valve is letting water back in sump and unit then tries to drain.
